The article is devoted to the assessment of the transport capabilities of inland waterways on the example of the Siberian region. As the main indicator of this assessment, the authors propose the product of the coefficient of the class of the depth of the ship's course of the river for the period of its operation. The introduction contains the normative documents on the basis of which the proposed methodology is based. It is proposed to calculate the resource of rivers according to two options: in the first – the guaranteed depth of the ship's course is used, in the second - the change in the class of the depth of the ship's course of the river during the entire navigation is taken into account. Based on the proposed methodology, calculations of the resources of the four main Siberian rivers were made. Thanks to this indicator, it became possible to calculate and compare the resources of rivers with different periods of operation and different depths of the ship's course. The Lena River has the least resource in the region, since its upper reaches are sharply limited by the depth of the ship's passage, and the lower reaches by the period of operation.

The article discusses the issues of developing methodological foundations in the study of the possibility of involving newly developed areas in a single transport network of the country. The synergetic approach, the use of methods and algorithms of nonlinear dynamics allows us to study the functioning of transport systems in conditions of possible risks and losses, to find bifurcation values that determine the structural instability of dynamic transport systems. The authors identified the areas of gravity of oil and gas condensate fields, which were assigned to the base ports of service included in the system of the international transport corridor "Northern Sea Route". The transport infrastructure of each base port is considered, and it is revealed that the internal water transport plays an important role in their maintenance, without the participation of which the functioning of the considered areas of gravity will be difficult or practically impossible. Three schemes of operation of the transport fleet are proposed route and non-route.
